Eli phepha lixoxa ngobume bangoku, impumelelo yamva nje kunye nophuhliso lwexesha elizayo lwetekhnoloji ye-electro optic modulator
Umzobo 1: Ukuthelekisa ukusebenza kwezinto ezahlukeneyoimodyuli yokubonaubuchwepheshe, kubandakanywa ifilimu encinci ye-lithium niobate (TFLN), i-III-V i-modulators yokufunxa umbane (EAM), i-silicon-based kunye ne-polymer modulators ngokwemiqathango yokulahleka kokufakwa, i-bandwidth, ukusetyenziswa kwamandla, ubukhulu, kunye nomthamo wokuvelisa.
Iimodyuli ze-silicon ezisekelwe kwi-electro optic zemveli kunye nokulinganiselwa kwazo
Iimodyuli zokukhanya ze-Silicon ezisekelwe kwi-photoelectric zibe sisiseko seenkqubo zonxibelelwano ze-optical iminyaka emininzi. Ngokusekelwe kwimpembelelo ye-plasma yokusabalalisa, ezo zixhobo zenze inkqubela ephawulekayo kwiminyaka eyi-25 edlulileyo, ukwandisa amazinga okudluliselwa kwedatha ngemiyalelo emithathu yobukhulu. Iimodyuli zanamhlanje ezisekelwe kwi-silicon zinokufikelela kwi-4-level pulse amplitude modulation (PAM4) ukuya kuthi ga kwi-224 Gb / s, kwaye nangaphezulu kwe-300 Gb / s kunye ne-PAM8 modulation.
Nangona kunjalo, iimodyuli ezisekwe kwisilicon zijongene nemida esisiseko evela kwiipropathi zezinto eziphathekayo. Xa i-transceivers optical ifuna amazinga e-baud ngaphezu kwe-200 + Gbaud, i-bandwidth yezi zixhobo kunzima ukuhlangabezana nemfuno. Lo mda uvela kwiipropati zendalo ze-silicon - ibhalansi yokuphepha ukulahleka kokukhanya okugqithisileyo ngelixa ukugcinwa kwe-conductivity eyaneleyo kudala i-tradeoffs engenakuphepheka.
Itekhnoloji yemodyuli esakhulayo kunye nemathiriyeli
Imida yeemodyuli ezisekelwe kwi-silicon ziye zaqhuba uphando kwezinye izinto kunye nobuchwepheshe bokudibanisa. Ifilimu encinci i-lithium niobate iye yaba lelona qonga lithembisayo kwisizukulwana esitsha semodyuli.Ifilimu encinci ye-lithium niobate electro-optic modulatorsilifa iimpawu ezigqwesileyo isambuku lithium niobate, kubandakanywa: ifestile elubala ebanzi, i-coefficient electro-optic enkulu (r33 = 31 pm/V) linear cell isiphumo Kerrs inokusebenza kuluhlu lwamaza amaninzi
Inkqubela phambili yakutshanje kwifilimu encinci ye-lithium niobate iteknoloji iye yavelisa iziphumo eziphawulekayo, kubandakanywa imodyuli esebenza kwi-260 Gbaud kunye namazinga edatha ye-1.96 Tb / s ngetshaneli nganye. Iqonga lineenzuzo ezizodwa ezifana ne-CMOS-compatible drive voltage kunye ne-3-dB bandwidth ye-100 GHz.
Isicelo setekhnoloji esakhulayo
Ukuphuhliswa kweemodyuli ze-electro optic kuhambelana ngokusondeleyo nezicelo ezivelayo kwiindawo ezininzi. Kwintsimi yobukrelekrele bokwenziwa kunye namaziko edatha,iimodyuli ezinesantya esiphezuluzibalulekile kwisizukulwana esilandelayo soqhagamshelwano, kwaye izicelo ze-AI zekhomputha ziqhuba imfuno ye-800G kunye ne-1.6T i-transceivers pluggable transceivers. Itekhnoloji yemodyuli iyasetyenziswa: quantum information processing neuromorphic computing Frequency modulated continuous wave (FMCW) lidar microwave photon technology
Ngokukodwa, ifilimu encinci ye-lithium niobate i-electro-optic modulators ibonisa amandla kwii-injini ze-optical processing computational, ibonelela ngokumodareyitha okukhawulezileyo okukhawulezileyo okukhawulezisa ukufundwa koomatshini kunye nokusetyenziswa kobukrelekrele bokwenziwa. Iimodyuli ezinjalo zinokusebenza kumaqondo aphantsi kwaye zifanelekile kwi-quantum-classical interfaces kwimigca ye-superconducting.
Uphuhliso lwesizukulwana esilandelayo seemodyuli ze-electro optic zijongene nemingeni emininzi emikhulu: Iindleko zemveliso kunye nesikali: iimodyuli ze-lithium niobate zefilim ezincinci okwangoku zilinganiselwe kwimveliso ye-wafer eyi-150 mm, ekhokelela kwiindleko eziphezulu. Ishishini kufuneka landise ubungakanani be-wafer ngelixa ligcina ukufana kwefilimu kunye nomgangatho. Ukudityaniswa kunye noyilo oludibeneyo: Uphuhliso oluyimpumelelo lweiimodyuli ezisebenza kakhuluifuna izakhono zoyilo olubanzi, ezibandakanya intsebenziswano ye-optoelectronics kunye nabayili be-chip ye-elektroniki, ababoneleli be-EDA, imithombo, kunye neengcali zokupakisha. Ubunzima bokuvelisa: Ngelixa iinkqubo ze-silicon-based optoelectronics zingantsonkothanga kakhulu kunezobuchwephesha be-CMOS eziphambili, ukufezekisa ukusebenza okuzinzileyo kunye nesivuno kufuna ubuchwephesha obubalulekileyo kunye nokuphuculwa kwenkqubo yokuvelisa.
Iqhutywa yi-AI boom kunye ne-geopolitical factor, intsimi ifumana utyalo-mali olwandisiweyo oluvela koorhulumente, ishishini kunye necandelo labucala kwihlabathi jikelele, ukudala amathuba amatsha okubambisana phakathi kwezemfundo kunye nezoshishino kunye nokuthembisa ukukhawulezisa ukutsha.
